We present a case of appendicitis within a De Garengeot hernia. The patient presented to the emergency department with 4 days of worsening abdominal pain. Computed tomography examination revealed an inflamed appendix within a femoral hernia. The patient underwent appendectomy and repair of the femoral defect. Pathological examination was consistent with acute appendicitis. De Garengeot hernia is a rare phenomenon, with less than 5% of femoral hernias containing the appendix and 0.08% to 0.13% containing an incarcerated acute appendicitis.
